So what of he has ASD?That's not some crazy condition that forces people to be nasty cheating bastards!You're not leaving a man with ASD, you're leaving a cheat.

Just go.Frankly, fuck that his family thinks.The only thing I'd do about them is tell them that X is the day you're telling him it's over, so please arrange to be physically present in case he needs immediate support with his mental health.

ASD covers loads, this is the first time I've heard of it being used to bash the DW of someone who is casting his net to catch dates

It doesn't matter what he has, what he is diagnosed with or what his excuses are.

You decide where your line is mine would absolutely include online dating and if he crosses it then you must decide whether to stay and be held ransom or move on and find someone who will make you happy.

I'm no expert, I am an Autist though and I do know several others on the spectrum and although we can be obtuse about feelings and massively selfish I find it hard to believe that someone with an adult diagnosis suffers from such a niche and extreme compulsion.Imho it's a smoke screen so he can have his cake and eat it.
